Henry Mulwray was a Human who lived in the 23rd century. In the 2290s, Mulwray manufactured defensive weaponry for Starfleet and was rumored to have made wealth by selling arms to non-Federation customers.
In 2293, Federation President Ra-ghoratreii consulted with Mulwray, after it appeared the Federation would soon be involved in a war with the Klingons after James T. Kirk and Leonard McCoy were charged with the murder of Gorkon. Mulwray reported that, in the event of war, his factories could begin full production within a week. Sarek was concerned at Mulwray's presence at the meeting, as it seemed to him that now even civilians were preparing for war. (ST novelization: Star Trek VI: The Undiscovered Country)
